Arduino – MIDI – piezo sensors – Garage Band

For now, I want to record a couple of thoughts that might be useful later:

From the immensely useful phasor~ mailing list:
Here is a good straight forward video about soldering leads onto piezo discs
to make contact mics and pickups. It may prove a useful reference in
